See: Hair follicle.

A sac or pouch-like cavity formed by a group of cells. In the ovaries, one follicle contains one egg. In the skin, one follicle contains one hair.

(fol-eh-kul) A microscopic structure in the ovary that contains the developing ovum and secretes estrogens.

Blisterlike, fluid-filled structure in the ovary that contains the egg.

stimulating hormone (FSH) - Hormone produced and released by the anterior pituitary that stimulates the development of the follicle in the ovary.

early 15c., in anatomy, "small sack," from Latin folliculus "a little bag," diminutive of follis "bellows, inflated ball, money-bag," from PIE *bhol-n-, suffixed form of [..]

A cavity and sac in the ovary that contains a maturing egg.

small, protective sac, gland, or cluster of cells. In humans, hair grows from hair follicles, while teeth develop from dental follicles.

A small dry fruit opening down one edge. Focal plant

A dry, dehiscent (splits open at maturity) fruit derived from one carpel that splits along one suture.

the name that is given to the cluster of cells that protect and nourish the cell or the structure that is inside it.

The hair follicle houses the root of the hair.

A small group of cells that surrounds and nourishes a structure such as a hair or a cell such as an egg.

The pocket or tubular cavity in the skin surface from which the hair or wool grows.

[Indumentum (hairs, etc.)] -- Type of dehiscent often many-seeded fruit developing from one carpel, splitting along one line (like some pods).

each month, an egg develops inside the ovary in a fluid filled pocket called a follicle. This follicle releases the egg into the fallopian tube.

(n) any small spherical group of cells containing a cavity

  A spherical mass of cells usually containing a small cavity

A group of cells that form a small sac.

The part of the ovary where the egg develops.

A cluster of cells.

Part of the skin which contains the root of a hair. (Modern)

A small shaft in the skin through which a hair grows, through which sebum is excreted from sebaceous glands to the surface of the skin. Follicles become blocked in the process of acne.

A degenerating Ovarian Follicle as a result of atresia (Follicular Atresia). During atresia, the Oocyte and Granulosa Cells within the basal lamina die and are replaced by fibrous Tissue.

Dense fibrous layer formed from mesodermal Tissue that surrounds the epithelial Enamel Organ. The Cells eventually migrate to the external surface of the newly formed root Dentin and give rise to the [..]

The Blister-like mature Ovarian Follicle containing the Ovum surrounded by an accumulation of Granulosa Cells (the cumulus oophorus) and an increasing volume of Follicular Fluid. The mature Graafian f [..]

A tube-like invagination of the Epidermis from which the Hair shaft develops and into which Sebaceous Glands open. The Hair follicle is lined by a cellular inner and outer root sheath of epidermal ori [..]

An Oocyte-containing structure in the cortex of the Ovary. The Oocyte is enclosed by a layer of Granulosa Cells providing a nourishing microenvironment (Follicular Fluid). The number and size of folli [..]

A crypt or minute cul-de-sac or lacuna, such as the depression in the skin from which the hair emerges.

A sac or pouch-like cavity formed by a group of cells. In the ovaries, one follicle contains one egg. In the skin, one follicle contains one hair.

 A very small sac or gland; in follicular lymphoma the term relates to the appearance of groups or clusters of lymphoma cells seen under the microscope when a biopsy sample is examined

A fluid-filled sac in the ovary where the egg grows before it is release during ovulation.

The hair follicle houses the root of the hair.A pore in the skin from which a hair grows.

A cluster of cells which surround, protect and nourish a developing egg cell in the ovary and also secrete oestrogen.

a small, narrow cavity or sac in an organ or tissue, such as the ones on the skin that contain hair roots or the ones in the ovaries that contain the developing eggs

1) A fluid-filled structure in the ovaries that contains a developing egg. 2) A pore in the skin from which a hair grows. The hair follicle houses the root of the hair.

The sac of fluid that surrounds the egg and which can usually be seen on the ultrasound scan.

A fluid-filled pocket in the ovary that acts as a house for the microscopic egg. Each ovary has many follicles within it. Follicles start out extremely small and then grow larger under the influence of hormones. They are lined with granulosa cells which produce estrogen and nourish the oocyte. Each follicle contains a single ooctye.

The cells surrounding a developing egg in the ovary.

A cavity in the ovary that contains a maturing egg.

a small cavity, sac, or gland, such as a hair follicle or ovarian follicle. The latter secretes hormones, estrogen and progestin, that regulate the menstrual cycle. See also graafian follicle.
